ABSTRACT:
The invention provides a fall arrest device for pole climbers consisting of a yoke for engagement with a pole on the side opposite the climber and two arms attached to respective ends of the yoke. Each arm carries a rotatable engagement structure and strap attachment means so that tension in an associated strap, to connect the climber's waist belt to the device, will bring the arms towards one another and the engagement structures will be forced against the pole to hold the device in position to support the climber. Also, the invention provides a fall arrest device having safety elements passing through the device between the strap attachments so that if the device breaks the safety elements continue to provide a mechanical link around the pole.
